Performance & Applications:
1. Polyethylene glycol series products can be used for pharmaceuticals. Relatively low molecular weight polyethylene glycol can be used as solvent, co-solvent, o/w emulsifier and stabilizer, used to make cement suspension, emulsion, injection, etc., also used as water- soluble ointment matrix and suppository matrix, relatively high molecular weight solid waxy polyethylene glycol is often used to increase the viscosity and solidification of low molecular weight liquid PEG, as well as compensation for other drugs. For drugs that are not easy to dissolve in water, this product can be used as a carrier of solid dispersion to achieve the purpose of solid dispersion, PEG4000, PEG6000 is a good coating material, Wrap hydrophilic polishing material, membrane and capsule, plasticizer, lubricant and drop pill matrix, used in the preparation of tablets, pills, capsules, microcapsules, etc.
2. Polyethylene glycol series products can be used as raw materials for ester surfactants .
3. PEG-200 can be used as a medium for organic synthesis and a heat carrier with high requirements, and is used as a wetting agent, inorganic salt solubilizer and viscosity modifier in the daily chemical industry. Used as a softener and antistatic agent in the textile industry. It is used as a wetting agent in the paper and pesticide industry.
4. PEG-400, PEG-600, PEG-800 are used as substrates for medicine and cosmetics, lubricants and wetting agents for rubber industry and textile industry. PEG-600 is added to electrolyte in the metal industry to enhance the grinding effect and enhance the gloss of the metal surface.
5. PEG- 1000 and PEG- 1500 are used as substrates or lubricants and softeners in the pharmaceutical, textile and cosmetic industries; Used as a dispersant in the coating industry, improve the water dispersibility and flexibility of the resin, the dosage is 20-30%，The ink can improve the solubility of the dye and reduce its volatility, especially suitable in wax paper and ink pad, and can also be used in ballpoint pen ink to adjust the ink viscosity; In the rubber industry as a dispersant, promote.vulcanization, used as a dispersant of carbon black filler.
6.PEG-2000 is used as metal processing casting agent. metal wire drawing, stamping or forming lubricant and cutting fluid,grinding cooling lubricant, polishing agent ,welding agent, etc. lt is used as a lubricant in the paper industry, and also as a hot melt adhesive to increase rapid rewetting capacity.
